Specification of Letters Patent.

Patented Aug. 23, 1921.

Application led June 6, 1919. Serial No. 302,235.

T o all 'whom t may concern Be it known that I, DAVID F. HAGERTY, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented a new and useful Piano-Mover, of which the following is a specification.

This invention relates to apparatus for use in moving pianos and like heavy structures, one of the objects of the invention being to provide a device of this character' whereby a piano or the like can be moved readily to or from a van or truck and by means of which the load can be easily conveyed up o1' down a stairway.

A further object is to provide a device of this character which will prevent the object being hauled from becoming injured, the movement of said structure being easily controlled at all times.

A further object is to provide a moving device of this character which is simple, durable and compact in construction and will not readily get out of order.

lith the above and other objects and advantages in mind, the invention consists of combinations of elements, arrangements of parts, formations and operations, and general assemblage, which will be hereinafter enlarged upon and recited in the appended. claim.

On the drawings Figure 1 is a side elevation of my improved moving device in operative position on the tail gate of a van and in position to receive a piano or other structure from the van;

Fig. 2 is a fragmentary plan view of the device showing its manual operating mechanism;

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1;

Fig. a is a vertical sectional view of one of the supporting standards;

Fig'. 5 is a transverse section al view taken through one of the side members of the frame on line 5-5 of Fig. 2; and

Fig. 6 is an end elevation of the device in operative position on the end gate of the van.

On the drawing, wherein like characters of reference denote like parts en all of the views, the numeral 5 designates a pair of parallel side beams connected together by cross bars 6. Journaled in the end portions of the beams 5 are transverse shafts 7. Pulleys or wheels 8 are mounted on these shafts adjacent their ends and mounted on them are endless belts 9.

Standards 10 are mounted at the lower ends of the side beams and journaled therein is a shaft 11 upon which is secured a sprocket wheel 12 engaged by a sprocket chain 13 passing around a second sprocket wheel 14 fixed upon the shaft 7 at the lower end of the side beams 5. A crank handle 15 is attached to the shaft 11 and by means thereof it is possible to move the belts.

Feet 16 are provided to support the outer ends of the side beams above the pavement or floor and are detachably engaged with the extremities of the lower shaft 7. Supporting members 17 are formed at the upper ends of the side bars and are adapted to engage the end gate of the van and support the device in the position illustrated in Fig. 1.

A carrier 18 having an upstanding back 19 at one end thereof is provided which is secured to the endless belts through the medium of bolts 20 and is adapted to traverse the length of the beams 5 with the load supported thereon.

The embodiment of the invention illustrated and described is considered the preferred construction, but it will 'be understood that the same may be modified in many respects and that such limits of modification are governed only by what is claimed.

What is claimed is A device of the class described including side members, support engaging members diverging from one end of each side member, connections between the side members, transverse shafts carried by the end portions of the side members, supports detachably engaged by the end portions of one of the shafts, pulleys on the shafts, endless belts mounted on the pulleys cross strips connecting the belts, a carrier secured on the cross strips and having an upstanding portion, said carrier being parallel with the belt, an upstanding portion lixedly connected to the side members at one end thereof and means carried by said last mentioned upstanding portion and one of the shafts for driving the belts to move the carrier longitudinally of the side members.

ln testimony that l claim the foregoing as .my own, l have hereto affixed my signature in the presence of two witnesses.
